Abstract
Abstract A sealed electrical connector includes one connector member having an oval-shaped cavity containing electrical contacts. A second connector member has a main body of a similar oval shape and having electrical contacts for mating with the contacts in the other connector member. A circular sealing boot is inserted into the cavity so as to deform to the oval shape, thereby providing lateral forces against the cavity wall which ensures that the sealing boot is retained in the cavity and promotes a tight seal when the main body of the second connector member is inserted into the cavity. The sealing boot is formed with elastomeric material into a circular cylindrical shape and is retained in the cavity even when the connector is disconnected.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
A sealed electrical connector having a longitudinal insertion axis, comprising: a first connector member having a front face, a plurality of first electrical contacts extending parallel to said longitudinal axis and meeting said front face, and a shroud extending from said front face annularly of said longitudinal axis, an inner wall of said shroud having a substantially oval shape as viewed in cross section perpendicular to said longitudinal axis; a sealing boot received within said shroud, said sealing boot formed to have a substantially circular shape as viewed in cross section perpendicular to said longitudinal axis, said sealing boot having an outer cylindrical surface deformed by said shroud into a substantially oval shape conforming to said inner wall of said shroud; and a second connector member having a plurality of second electrical contacts extending parallel to said longitudinal axis and contacting said first electrical contacts, said second connector member having a substantially oval-shaped perimeter engaging an inner cylindrical surface of said sealing boot.
Claim 2
Dependent Claim
163 words
A sealed electrical connector having a longitudinal insertion axis, comprising: a first connector member having a front face, a plurality of first electrical contacts extending parallel to said longitudinal axis and meeting said front face, and a shroud extending from said front face annularly of said longitudinal axis, an inner wall of said shroud having a substantially oval shape as viewed in cross section perpendicular to said longitudinal axis; a sealing boot received within said shroud, said sealing boot formed to have a substantially circular shape as viewed in cross section perpendicular to said longitudinal axis, said sealing boot having an outer cylindrical surface deformed by said shroud into a substantially oval shape conforming to said inner wall of said shroud; and a second connector member having a plurality of second electrical contacts extending parallel to said longitudinal axis and contacting said first electrical contacts, said second connector member having a substantially oval-shaped perimeter engaging an inner cylindrical surface of said sealing boot.
Claim 3
Dependent Claim
37 words
The connector of claim 1 wherein said first electrical contacts are comprised of male terminal pins extending from said front face and wherein said second electrical contacts are comprised of female terminal sockets located within said perimeter.
Claim 4
Dependent Claim
19 words
The connector of claim 1 wherein said sealing boot is substantially cylindrically shaped and includes a plurality of ribs.
Claim 5
Dependent Claim
24 words
The connector of claim 1 further comprising retaining means coupled to said connector members for retaining said connector members in a fully engaged position.
Claim 6
Dependent Claim
27 words
The connector of claim 1 wherein said sealing boot has an undeformed outer circumference substantially equal to or slightly greater than said inner circumference of said shroud.
Claim 7
Dependent Claim
25 words
The connector of claim 5 wherein said outer circumference of said sealing boot is substantially one percent greater than said inner circumference of said shroud.
Claim 8
Independent Claim
155 words
A method of establishing a sealed connection in an electrical connector having a substantially oval-shaped cross section, said connector including a first connector member, a second connector member, and a sealing boot, said first connector member having a plurality of first electrical contacts and a shroud having a substantially oval-shaped inner wall annularly surrounding said first electrical contacts, said second connector member having a plurality of second electrical contacts and having a substantially oval-shaped perimeter for fitting within said inner wall of said shroud, said method comprising the steps of: providing said sealing boot with a substantially circular cylindrical shape; inserting said sealing boot into said shroud so as to deform said sealing boot into a substantially oval shape; and inserting said second connector member into said sealing boot and said shroud so as to join said first and second electrical contacts and to establish a seal between said shroud and said second connector member.
Claim 9
Independent Claim
155 words
A method of establishing a sealed connection in an electrical connector having a substantially oval-shaped cross section, said connector including a first connector member, a second connector member, and a sealing boot, said first connector member having a plurality of first electrical contacts and a shroud having a substantially oval-shaped inner wall annularly surrounding said first electrical contacts, said second connector member having a plurality of second electrical contacts and having a substantially oval-shaped perimeter for fitting within said inner wall of said shroud, said method comprising the steps of: providing said sealing boot with a substantially circular cylindrical shape; inserting said sealing boot into said shroud so as to deform said sealing boot into a substantially oval shape; and inserting said second connector member into said sealing boot and said shroud so as to join said first and second electrical contacts and to establish a seal between said shroud and said second connector member.
